Impact of Glomus Fasciculatum and Fluorescent Pseudomonas on Growth Performance of Vigna Radiata (L.) Wilczek Challenged with Phytopathogens

Abstract

Impact ofGlomus Fasciculatumand FluorescentPseudomonason Growth Performance ofVigna Radiata(L.) Wilczek Challenged with Phytopathogens: Fusarium oxysporumandRhizoctonia solaniare the major soil-borne pathogens causing growth and yield depression. The present study focused on the ability of fluorescentPseudomonasandGlomus fasciculatumon growth performance ofVigna radiatain pathogen-infested soil. The percent colonization byG. fasciculatumindicated an increase of the presence of fluorescentPseudomonasand a decrease of the presence ofFusarium oxysporumorRhizoctonia solani. However, the reduction of colonization induced pathogen in percent was alleviated by fluorescentPseudomonas. Inoculation with either fluorescentPseudomonasorG. fasciculatumor both induced a significant increase in root and shoot length, plant vigour index, dry weight and total N and P content in V. radiata as compared to uninoculated control. The impact of inoculation was much pronounced in dual inoculated plants in comparison with those inoculated with eitherG. fasciculatumor fluorescentPseudomonas. In contrast, treatment of plants with eitherF. oxysporumorR. solanidecreased the root and shoot length, plant vigour index, dry weight and total N and P content in the test legume. However, in the presence of fluorescentPseudomonasandG. fasciculatum, the adverse effect on the pathogens on growth ofV. radiatawas alleviated.
